Cocos2d iphone [\uu NSCFDictionary setObject:forKeyedSubscript:]：发送到实例0x6a39930的选择器无法识别

我想在我的项目中实现chartboost&我有一个来自

我已在appdelegate中添加了我的cb.appId和cb.appSignature 但当我运行这段代码时，它显示了错误[\uu NSCFDictionary setObject:forkeydsubscript:] 我已经使用断点调试进行了检查，它在ExampleApppDelegate.m中的代码之后显示错误

    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:    (NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.
    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
        self.viewController = [[ExampleAppViewController alloc] initWithNibName:@"ExampleAppViewController_iPhone" bundle:nil];
    } else {
        self.viewController = [[ExampleAppViewController alloc] initWithNibName:@"ExampleAppViewController_iPad" bundle:nil];
    }
    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];
    return YES;
}

那么，在appdelegate中，我应该修改什么来克服这个错误呢

在appdelegate.m中的项目中，我在ApplicationIDBecMeactive方法中添加了此代码，我添加了以下代码以包括chartboost

-(void) applicationDidBecomeActive:(UIApplication *)application
{
    Chartboost *cb = [Chartboost sharedChartboost];

    cb.appId=@"51c3e47d17ba475b0b000002 ";
    cb.appSignature=@"392392796fb9a1603bcd2deb0aa9a17442ccd83d";

    // Begin a user session. Must not be dependent on user actions or any prior network requests.
    [cb startSession];

    // Show an interstitial
    [cb showInterstitial];
    if( [navController_ visibleViewController] == director_ )
        [director_ resume];
}

但仍然会出现同样的错误

您是否尝试过将编译器更改为“Apple LLVM compiler 4.2”？嘿，问题解决了。这是ios版本的问题，当我在ios-6上尝试它时，它没有显示任何错误。谢谢你的回复
